VESA Screws for TV Mounting

You buy a TV mount, hang it on the wall, and attach your TV. But the screws that came with the mount do not fit the holes on the back of your TV. The threads are too wide, too narrow, or the wrong length. The mount is secure on the wall, but you cannot safely attach your TV to it because the VESA screws do not match.

VESA screws are not universal. Different TV sizes and brands use different screw sizes — M4, M6, or M8 — and different thread lengths. Using the wrong VESA screws can strip the TV mounting threads, damage the TV back panel, or leave the TV insecurely attached to the mount. In Chicago, where DIY TV mounting is common, VESA screw mismatches are one of the most frequent reasons we are called to fix a failed installation.

Quick Answer: What VESA Screws Do I Need?

Most TVs use M4 screws (32-43 inch TVs), M6 screws (50-65 inch TVs), or M8 screws (70+ inch TVs). The screw length should match the depth of the threaded hole on the back of your TV — typically 7mm to 12mm. Using screws that are too long can damage internal TV components. Using screws that are too short will not securely hold the TV. Check your TV manual for the exact screw specification.

VESA Screw Sizes Explained

VESA screws are metric screws, designated by diameter and thread pitch. The “M” number indicates the diameter in millimeters.

M4 screws (4mm diameter). Used on most 32 to 43-inch TVs. The most common size for small and mid-size TVs. Thread depth is typically 7 to 10mm. If your TV has small, narrow mounting threads, it almost certainly uses M4 screws.

M6 screws (6mm diameter). Used on most 50 to 65-inch TVs. The most common size for mid-size and large TVs. Thread depth is typically 8 to 12mm. If your TV has medium-width mounting threads, it likely uses M6 screws.

M8 screws (8mm diameter). Used on most 70 to 85-inch TVs. The largest standard VESA screw size. Thread depth is typically 10 to 14mm. If your TV has wide, heavy-duty mounting threads, it uses M8 screws.

VESA Screw Length: The Hidden Problem

Even if you have the correct screw diameter (M4, M6, or M8), the screw length matters just as much. VESA screw lengths are measured from the bottom of the head to the tip of the screw.

Standard lengths. Most VESA screws come in lengths of 7mm, 8mm, 10mm, 12mm, and sometimes 14mm. The correct length matches the depth of the threaded hole in your TV.

Screws that are too long. If the screw is longer than the threaded hole, it will bottom out before fully engaging the threads. This can crack the TV back panel, damage internal components, or short-circuit electronics behind the panel.

Screws that are too short. If the screw is shorter than the threaded hole, it will not engage enough threads to hold the TV securely. The TV may feel attached but can loosen over time and fall.

How to Identify Your TV’s VESA Screw Size

Check the TV manual. The specifications section lists the VESA screw size and recommended length. This is the most reliable method.

Search your TV model online. If you do not have the manual, search for your TV model number plus “VESA screw size” or “mounting screw specification.” The manufacturer website or retailer product page will list the screw size.

Measure the existing screws. If your TV still has the factory stand attached, the stand mounting screws are often the same size as the VESA screws. Remove one and measure the diameter and length with calipers or a metric ruler.

Use a screw gauge. A metric screw thread gauge can identify the exact diameter and thread pitch. Hardware stores carry these tools.

VESA Spacers: When and Why

Some TVs require spacers (also called standoffs or washers) between the screw head and the TV back panel. Spacers serve two purposes:

Length extension. If the screw is slightly too long, a spacer can take up the extra length so the screw does not bottom out in the TV.

Load distribution. Spacers distribute the clamping force over a larger area of the TV back panel, reducing the risk of cracking or denting thin plastic panels.

Most quality TV mounts include a set of spacers in different lengths (typically 5mm, 10mm, 15mm). Use the spacer that allows the screw to fully engage the TV threads without bottoming out.

What Is Included in Professional TV Mounting

• TV VESA screw size identification — we verify the exact screw diameter and length for your TV model.
• Correct VESA screws and spacers — we bring the right screws for your TV, not just the ones that came with the mount.
• Mount selection compatible with your TV’s VESA pattern and weight.
• Wall structure assessment and appropriate anchor selection.
• Complete installation, leveling, and cable management.
• Stability verification before you use the TV.

When TV Mounting Requires Specialized Help

• Stripped VESA threads. If the threads on the back of your TV are stripped from a previous installation attempt, repair may be possible but requires specialized techniques.
• Curved back panels. Curved TVs often require longer screws and special spacers to bridge the gap between the curved panel and flat mount.
• Ultra-thin TVs. Some ultra-thin TVs have very shallow threaded holes that require short screws and precise installation.
• Missing or damaged screws. If the original VESA screws are lost or damaged, replacement screws must match the exact specification.

Our TV Mounting Process

Step 1: TV and wall assessment.
We verify your TV model, VESA pattern, screw size, and wall structure. We identify the exact screws and spacers needed before we begin.

Step 2: Mount selection.
Based on your TV’s VESA pattern, weight, and desired mount style, we select a compatible mount. We verify the mount includes the correct VESA screws or bring our own.

Step 3: Mount installation.
The mount is secured to the wall using anchors appropriate for your wall type. We verify the mount is level and solid before attaching the TV.

Step 4: TV mounting and cable management.
Using the correct VESA screws and spacers, your TV is securely attached to the mount. All cables are organized and we perform a final stability check.

Pricing Factors

• TV size and weight. Larger, heavier TVs require heavier-duty mounts and hardware.
• Mount type. Fixed mounts are the most affordable. Tilting and full-motion mounts cost more.
• Wall type. Standard drywall on wood studs is the most straightforward. Metal studs, plaster, brick, and concrete require specialized hardware.
• Cable management. Basic cable organization is included. In-wall cable concealment requires additional materials and labor.
• Special hardware. If your TV requires special VESA screws, spacers, or adapters, these add to the material cost.

FAQ: VESA Screws for TV Mounting

Q: What size screws does my 55-inch TV need?
A: Most 55-inch TVs use M6 screws, typically 8mm to 12mm in length. Check your specific model in the manual or online, as some brands vary.

Q: Can I use longer screws if the exact length is not available?
A: No. Longer screws can damage the internal components of your TV. If the exact length is not available, use spacers to extend the effective length of a shorter screw instead.

Q: The screws that came with my mount do not fit. What should I do?
A: Do not force them. The mount screws may not match your TV’s specification. Check your TV manual for the correct screw size and source the correct screws. We carry a full range of VESA screws and can help.

Q: Do I need spacers?
A: Many TVs benefit from spacers. Spacers protect the TV back panel and ensure the screw engages the correct number of threads. If your TV has a curved back or thin panel, spacers are especially important.

Q: Can I use wood screws instead of VESA screws?
A: No. Wood screws have different thread profiles and can strip the TV mounting threads. Always use metric machine screws (M4, M6, or M8) with the correct thread pitch.

Q: How much does professional TV mounting cost?
A: TV mounting pricing depends on TV size, mount type, wall type, and cable management needs. We bring the correct VESA screws for your TV — no extra charge for the right hardware. Call (708) 475-2454 or message us on WhatsApp.
